All lanes of Interstate 65 near Martin Luther King Jr. Street are back open after shutting down in both directions Thursday morning. In a tweet, Indiana State Police Sgt. John Perrine said a semi driving northbound struck an overhead sign, causing the sign to collapse on the southbound lanes.

Shortly after 11 a.m., one lane of traffic was moving in each direction, while two lanes each way remained closed.

Indiana Department of Transportation spokesman Scott Manning said I-65 was cleaned and all lanes reopened at around 4 p.m.

I-65 southbound is closed due to a crash. A northbound semi struck an overhead sign, causing the sign to collapse on the southbound side. All lanes of I-65 south will be closed at I-465. Please avoid the area

This is the second time an area interstate closed in recent months due to a fallen sign. On Sept. 21, westbound Interstate 70 on the east side closed for about seven hours after a dump truck driving with its bed raised smashed into an electronic message board.
